What are your system specs and the graphics settings you're using in the game? I'm still debating whether to buy the PC version or the 360 version. If I can get it to run good enough for online play on my 24" AL iMac, I'd buy the PC version.

tried the demo with most everything turned all the way up, and it was a little jumpy. ~10 fps. so i think i turned down a couple things and the resolution down to whatever resolution is under 1650x1080, and it ran a lot better

I've been playing the demo on my PC at 1920 x 1200 and highest settings. It runs and looks great.
Its an OC'd e6850 @ 4ghz w/ 4gb of ram and an OC'd 7900GT KO and a Raptor 150. I'm going to buy the full version after I beat crysis (which does not run so well ). But anyways, its a really sweet game.
